SPECIFICATION forming part of Letters Patent No. 765,313, dated July 19,1904.

Application. led July 20, 1903.

ming the faces of spoke-tenons; and the object of the invention is toproduce a simple, inexpensive, and effective machine of this class bywhich the spoke-tenons can be expeditiously and accurately cut to fitthe mortises of the wheel-hub in which they are to be placed. I attainthis result by the construction hereinafter described, and illustratedin the accompanying drawings, in which Figure 1 is a front elevation ofthe machine. Fig. 2 is a plan thereof with the lever 7 broken away.Figs. 3 and 4. are perspective views, respectively, oftheV cutter-knifeand one of the gage devices shown in the other views.

Referring to the said drawings by reference-numerals, 2 represents aframe which is rigidly secured by suitable bolts, such as 3, to a tabletand is provided with oppositely-disposed vertical slots 5, formingguideways for a cutter-knife 6. .The knife (see Figs. 1 and 3) isprovided with a diagonal or slanting cutting edge 6, which terminates atits lower corner in a transversely-arranged cutting-lip 6. 7 is a leverfulcrumed at-7 to a bracketarm 2 of the frame and extends across theframe, as clearly shown in Fig. 1, and its eX- tremity is formed into ahandle 7 C The arm 8, integral with the lever, projects in the oppositedirectionfrom the fulcrum and is connected to the table by an extensiblespring 8'.

Intermediate the handle and fulcrum the lever is connected by a link 9with the aforesaid knife, whereby the latter is forced down coincidentlywith the handle or raised by the resiliency of the spring when thehandle is released.

The slot in the portion of the frame forming the fulcrum for the leveroperating the Serial No. 166,236. (No model.)

'knife extends to or nearly to the table, while the opposite slot isshorter and terminates suiciently above the tabley as to permit thespoke or other material to be cut to pass directly under the shorterslot and knife. Thus it will be seen with this construction when theknife with the inclined cutting edge isv directly over the material tobe operated upon, and in starting the knife one has practically a pointfor a cutting edge to pierce the material and directly over the materialand a gradual increase of resistance until the point has passed throughthe spoke in the downward movement of the knife.

10 represents gage devices against which the spoke 11 (shown in positionto have its tenon trimmed) is held by a clamp-lever 12. The gage deviceseach comprise a block 13, which is advanced or withdrawn from the workby an adjustment screw 14, passing through a screw-threaded aperture 14/of a standard 15, integral with a base-plate 16, fixedly secured to thetable 4 by suitable fastenings, such as bolts 16. The block 13 isprevented from rotating with the adjustmentscrew by means of a guide-rod17, fixedly secured to the said block and extending through standards 15and 15. A thumb-screw 17 inserted in a corresponding aperture ofstandard 15, is provided to bear against the said guide-bar for lockingthe same and the block to which it is attached to any set position.

For convenience of manipulation I prefer-l ably provide a crank-handle18 to each of the said adjustment-screws. The clamp-lever 12 ispivotally connected through any of a series of holes 19/ positionedadjacent to one end by a pin or bolt 19 to a frame-support 20, securedto the table. The work is clamped by swinging the free end 21 of thelever 12 so as two edge thereon and press the same against theaforementioned gage-blocks.

22 is a stop for predeterminately placing the work longitudinally of thetable, so that the cut to be made upon the tenon and the shoulderthereof will coincide with the position of the knife. The said stoppreferably comprises a shank 22', extending through the web 2 of theframe and provided with a rectangular bend 22, whereby a larger area IOOis presented to thc spoke end. rI`he stop is secured to its set positionby a clamp-screw 23, fitted into a screw-tlireaded aperture 23 of theframe.

The operation of the device is extremely simply and will readily beunderstood from the foregoing description, taken in connection With thedrawings; but it may be pointed out that theV gag'es capable of being'independently set provide means for cutting tenons having parallel ortapering facesfor instance, by advancing or retracting either of thegages.

I do not wish to be understood as confining myself to the preciseconstruction hereinbefore described-as, for instance, to the manner ofoperating' the knife-actiiating lever by hand for a foot-pedal or othermeans may readily be substituted therefor.

Having described the invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a spoke-tenon trimmer, the combination of a horizontal table, of avertical guideframe having oppositelydisposed slots, one of which isshorter than the other, a bracket-arin made integral with saidfraine-section having the longer slot, a lever fulcruined on saidbracket-arm, a knife attached to said lever and reciprocating in saidslots, transverselyarranged gage devices, means to clamp the workagainst said gage devices and a longitudinally-adjustable stop-gagepassing through the lower end of the framework composing the longerslot, substantially as set forth.

2. In a spoke-tenon trimmer, the combination of a horizontal table, ofavertical guide? frame, havingI oppositely disposed slots, abracket-arn'i made integral with said frame, a lever fulcrumed on saidbracket-arm one end of which is connected to the table by a spring' andthe other end having a handle, a knife connected to said lever andreciprocating in said slots, of gage devices consisting of standards,adjusting-screws passing through said standards having blocks at theirends and an adjustable pivoted clamping-lever coperating with saidadjustable block, substantially as set forth.

8. In a spoke-tenon trimmer, the combination of a table of a guide-frameat right angles thereto having oppositelydisposed slots, a bracket-armmade integral with said frame, a lever fulcrumed on said bracket-arm oneend of which is connected to the table by a spring and the other endhaving a handle, a knife provided with an inclined edge terminating in arectangular lip connected to said lever and reciprocating in saidvertical slots, of gage devices consisting of standards, adjustingdevices passing through said standards,

an adjustable pivoted clamping-lever coperating with said adjustingdevices, and an adjustable stop, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
